QuarkChain — Super Scalable Secure Blockchain

in #blockchain6 years ago

QuarkChain is a high-throughput blockchain that aims to achieve millions of transactions per second (TPS).

Their ground breaking innovative permission-less blockchain architecture aims to meet the global-wise commercial standard. The QuarkChain team has extensive experience in developing powerful large-scale distributed systems in centralized world that handles billions of TPS.

Quarkchain Technology

Quarkchain contains elastic sharding blockchain layer, which contains a list of minor blockchains (shards). Each shard processes a sub-set of all transactions independently.

As number of shards increase, more transactions can be processed concurrently, thus, system capacity increases.

Root blockchain confirms all blocks from sharded blockchains. It does not process any transactions and has sufficiently strong difficulty so that reverting any transactions is not economically efficient.

It is designed to support additional shards in an active network which are easy and fast to add. Users will barely sense the adding of new shards.

Rootchain layer’s chain name is Rootchain and block name is Root block, interval is in minutes and main functionalities is Confirmation.

Sharding layer’s chain name is Shard and block name is Minor block, interval is in seconds and main functionalities is Ledger.

Security

Root chain’s 50% Hash power allocation enhances systems security and scalability and makes it more decentralized than single blockchain systems.

All transactions are protected by 50% of the overall hash power of the network, double spending attack requires at least 25% hash power of the entire network.

This is smaller than single-blockchains 50% but since Quarkchain is more decentralized as miners no longer need to join mining pools, it’s harder to collect 25% hash power compared to single-blockchain 50% hash power. It will also be extremely costly for a single entity to perform an attack.

Decentralization

QuarkChain is more decentralized than single blockchain Network.

Problem faced in other blockchain systems is that expected return times of weak miners grows as hash power increases thus they have to join pools which increases centralization.

Quarkchain solves this issue in a way that a weaker miner in Quarkchain doesn’t need to join a mining pool to collect its reward as Quarkchain allows collaborative mining.

Scalability

It dramatically scales the throughput of the network by advanced sharding to improve system capacity, system capacity can easily be increased to process even more TPS.

Roadmap and Timeline

Mar. 2018: Released Testnet 0.1 with Wallet 0.1. Testnet supports basic transactions including both in-shard and cross-shard transactions.

Q2 2018: Release Testnet 1.0 with smart contract support

Q4 2018: Release QuarkChain Core 1.0, Mainnet 1.0, together with Smart Wallet 1.0.

Q2 2019: Release QuarkChain Core 2.0, Mainnet 2.0, together with Smart Wallet 2.0.

Pros

  • Very experienced team
  • They are ahead of intended roadmap
  • They built the testnet which can achieve 2000+ TPS which means that until Q4 when is the mainnet launch, they can achieve what they are promising
  • As they are using EVM, dApps can be easily deployed on their network which can increase the value
  • Low hardcap (only $20m) for a project of such scale
  • Very hyped project

Cons

  • Competitors like Zilliqa and Ethereum (which plans to implement sharding)
  • Github is currently private

This is not an investment advice.

@therealwolf 's created platform smartsteem scammed my post this morning (mothersday) that was supposed to be for an Abused Childrens Charity. Dude literally stole from abused children that don't have mothers ... on mothersday.
